QUESTION A:
Find the GCD (or HCF) of numerator and denominator
GCD of 15 and 30 is 15
Divide both the numerator and denominator by the GCD
15 ÷ 15
30 ÷ 15
Reduced fraction:
1/2
Therefore, 15/30 simplified to lowest terms is 1/2.
Thus, <u>option d</u> is your answer
QUESTION B:
Find the GCD (or HCF) of numerator and denominator
GCD of 12 and 3 is 3
Divide both the numerator and denominator by the GCD
12 ÷ 3
3 ÷ 3
Reduced fraction:
4/1
Therefore, 12/3 simplified to lowest terms is 4/1 or 1/4.
Thus <u>option a</u> is your answer
